CAN Bus Example

[Mes-ser]

Look at this commit 7678bca
you can download nightly build from https://builds.renode.io/

And can confirm - It work, I used it.

PROTIP:
If you have multiple machines in emulation, then use CreateSocketCANBridge only in one of them, otherwise packets sent by them will cause infinite loop of packets.

I tried it with my stm32f4 which has a classic CAN and it's working.
Thanks for the help !

Example of flexcan https://github.com/renode/renode/blob/master/tests/peripherals/S32K3XX_FlexCAN.robot. There are other tests with CAN too.

Seems like F0 and H7 are the only ones with CANbus currently.

renode/platforms/cpus/stm32f0.repl

Line 167 in d02cf75

can: CAN.STMCAN @ sysbus <0x40006400, +0x400>

renode/platforms/cpus/stm32h743.repl

Line 280 in d02cf75

fdcan1: CAN.MCAN @ sysbus 0x4000A000

But STCAN is implemented here so maybe it is just a matter of just adding few lines to repl for F4 board (or STM32F103 in my case).

Thanks for the help but my question was if there is an example to connect a machine ( stm32f4 ) to the host through socketCAN, I mean by the host here is the machine running renode. For the example that you shared it was a communication between two emulated machines ( mr_canhubk3 ) communicating through an emulated CANhub on renode.
A communication between host and an emulated machine will be through the virtual CAN ( vcan ) it's a kernel module on linux machines, but I don't know if there is anyway to forward the canHub packets to the vcan.
